About this 0.51ct lab-grown radiant diamond

This 0.51ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG764610801 or 764610801. Listed at 21 retailers as of November 2, 2026, with prices from $310 to $2,449, a $2,139 spread on the same certified stone. MOH London lists it at $2,449. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
